Specific embodiment
For the ease of understanding the present invention, picture transmission method and system are become apparent from below with reference to relevant drawings,
It is fully described by.The preferred embodiment of picture transmission method and system is given in accompanying drawing.Picture transmission method and system can be with
Realized by many different forms, however it is not limited to embodiment described herein.Therefore, below in the accompanying drawings providing
The detailed description of embodiments of the invention is not intended to limit the scope of claimed invention, but is merely representative of the present invention
Selected embodiment.Based on embodiments of the invention, those skilled in the art institute on the premise of creative work is not made
The every other embodiment for obtaining, belongs to the scope of protection of the invention.
Embodiment 1
Fig. 1 shows the schematic flow sheet of picture transmission method provided in an embodiment of the present invention.
As shown in figure 1, picture transmission method provided in an embodiment of the present invention, is applied to long-range with picture shooting and picture
The digital camera of the intelligent terminal of transfer function, such as mobile phone, energy of being passed on Gong with figure, including：
Step S1, the photographing operation based on user generates a high definition picture, and detects whether current network is stablized.
Specifically, when user is taken pictures using intelligent terminals such as mobile phones, the pictorial information that user shoots, and root are obtained
A high definition picture is generated according to the pictorial information.It is appreciated that the pixel resolution of the high definition picture depends on concrete intelligence
The number of pixels of camera in terminal.Additionally, the pixel depth of the high definition picture depends on the color of display in intelligent terminal
Colour display screen shows system number, because the color displays system number of display determines the number of the color that the intelligent terminal can be represented.
For example, the colour of color monitor is synthesized into by three primary colours, it is assumed that the three primary colours R of certain color monitor is red, G is green
Color and B bluenesss represent that then the color monitor can represent 4096 kinds of different colors with 4 bits respectively.
Further, the pixel resolution and pixel depth of a high definition picture determine the data volume of the high definition picture, example
As one is secondary with very color (24), pixel resolution is the high definition picture of 1024*768, is not carrying out any digital compression etc.
Before processing, its data volume is about 2.25MB.Certainly, the data volume of high definition picture is also related to its size.Generally by intelligence
The data volume of the high definition picture that terminal is obtained is than larger.
Further, after user completes picture shooting, the change in signal strength frequency of current network is detected.The signal
Strength Changes frequency refers to that within the unit interval, current network is from the number of times that a change in signal strength is another signal intensity.Than
Compared with the change in signal strength frequency and the change frequency threshold value of storage of current network, so as to judge whether current network is stablized.Hold
It is readily understood, when the change in signal strength frequency of the current network reaches the change frequency threshold value, represent current network not
Stabilization；Conversely, representing current network stabilization.
Step S2, when the current network is unstable, compresses the high definition picture and generates a compressed picture, and send described
Compressed picture is to server.
If current network is unstable, compresses the high definition picture and generate a compressed picture.The data volume phase of the compressed picture
Data volume than high definition picture is generally smaller, and in the present embodiment, the data volume of compressed picture is usual in below 150Kb, so that
The transmission of compressed picture is to network bandwidth requirement than relatively low.
Specifically, the signal intensity of current network is detected.Signal intensity according to storage is interval and data-quantity threshold right
Should be related to, judge which signal intensity interval is the signal intensity of current network belong to, and obtain the intensity with the current network
Corresponding data-quantity threshold.The setting of data-quantity threshold is easy to make high definition picture different degrees of compression treatment, it is readily appreciated that,
Network signal intensity is lower, and corresponding data-quantity threshold is also smaller, so as to the compression degree to high definition picture is bigger.Certainly, when
Intelligent terminal transmit picture to carry out data transmission between server, or intelligent terminal when, can rule of thumb set and be best suitable for
The data-quantity threshold that picture is quickly transmitted.
Further, in the present embodiment, the compression to high definition picture includes two kinds of implementation methods.A kind of implementation method is drop
The resolution ratio of the low high definition picture, for example, colored high definition picture is converted to the high definition picture of black and white, so as to lower high definition
The data volume of picture.Specifically, the data volume data-quantity threshold corresponding with the signal intensity of current network of high definition picture is calculated
Difference, it is then disposable to complete the reduction of resolution ratio it is determined that the resolution sizes of required attenuating, or complete resolution ratio several times
Reduction, every time reduce designated value resolution ratio, until the data volume of the high definition picture be less than corresponding data-quantity threshold.
Another embodiment is that the high definition picture is cut, to reduce the size of the high definition picture, for example, cutting out
The frame or background of high definition picture are cut, so as to lower the data volume of high definition picture.It should be noted that the cutting to high definition picture
Should be premised on not changing the particular content of high definition picture.Certainly, the cutting to high definition picture can also be using existing to figure
The cutting of piece, in the way of the data volume for reducing picture, is not limited here.
Further, the data volume of the high definition picture after compression treatment is obtained, and compares the number of the high definition picture after treatment
Whether data-quantity threshold corresponding with the intensity of the current network is less than according to amount.When comparative result is no, after treatment
High definition picture makees further compression treatment, so repeatedly, until the data volume of the high definition picture after treatment is current less than with described
The corresponding data-quantity threshold of intensity of network.The data volume of high definition picture after treatment is less than the intensity with the current network
During corresponding data-quantity threshold, the compressed picture is generated based on the high definition picture after treatment.
In another embodiment, user can be said with attached certain text message according to the high definition picture for shooting for remarks
It is bright.Personnel are for example patrolled to find when there is poaching situation, can be with remarks poaching geographic area, poaching personal information, poaching object
Deng text information, it is easy to Surveillance center to understand abnormal conditions in time and provides treatment measures.In the present embodiment, the Surveillance center
It is arranged on server end.Generally, the data volume of text information is smaller, can be with compressed picture asynchronous transmission to server, this
In embodiment, after the transmission for completing text information, compressed picture to the server is sent.
Step S3, detects whether to receive the confirmation signal of the server feedback in Preset Time, works as testing result
For it is no when, perform step S2.
In the present embodiment, after compressed picture to server is sent, to whether sending and being successfully monitored.Specifically, exist
Detect whether to receive the confirmation signal of the server feedback in Preset Time, so as to judge whether server is properly received pressure
The data message of contract drawing piece.It is appreciated that when the confirmation signal of the server feedback is received in Preset Time, representing
The data message of compressed picture is successfully transmitted to server；Otherwise, it is necessary to resend, that is, step S2 is performed, until successfully sending out
Send the data message of compressed picture to server.
Step S4, when current network stabilization, the picture based on user sends operation and sends the high definition picture extremely
The server.
It should be noted that user need not carry out any upload operation in intelligent terminal, compressed picture is automatic after generation
Transmit to server, and whole compressed picture transmitting procedure in intelligent terminal operation system running background, user is simultaneously unaware of.
When generally current network is unstable, user can only be moved to the more stable network environment for being adapted to high definition picture transfer
High definition picture is sent behind position, it is clear that this mode, data transmission efficiency is low.The present embodiment is being worked as to the transmission means of picture
In the case of preceding unstable networks, transmission network bandwidth requirement will be first transmitted to server than relatively low compressed picture so that
Server can have a certain degree of understanding according to the compressed picture for receiving to pictorial information, greatly improve picture transfer effect
Rate, it is ensured that information transfer it is ageing.
It is appreciated that the information content that server can be known according to the compressed picture for receiving is not as good as high definition picture.This reality
Apply in example, whether the transmission to high definition picture depends on user.Specifically, during current network stabilization, user can supplement transmission
High definition picture is to server.Picture based on user sends operation and sends the high definition picture to the server.Easily find,
The present embodiment can realize that as many as user once-through operation completes the transmission of picture, reduce user's operation, and Consumer's Experience is relatively good.
